BARB Y W. BUTTERWORTH, JR., OI PHILADELPHIA, AND WILLIAM E. H. BELL, OF

GLENSIDE, PENNSYLVANIA, ASSIGNORS TO K. W. BUTTERWOR'IH & SONS COIM- IANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA APPARATUS FOB FLUID TREATING OR YARNS Application filed January 10, 1930. Serial nolnaeos.

This invention relates to apparatus for fluid treating or for dyeing yarns and more particularly to an apparatus especially adapted for use in denitration of nitro-cellulose yarns.

An important object of the invention is the production of apparatus of this character permitting ready insertion and removal of the yarn, providing for thorough contact of the yarn with the treating fluid and reducing the quantity of "treating fluid which must be employed.

A further and more specific object of the invention is to produce a novel and im-- proved yarn support facilitating the installation of the yarn in juxtaposition to a plurality of s ray pipes for treating the same and provi e a means for automatically connecting said spray pipes with a supply system upon insertion of the yarn support in the treating vat.

A further object of the invention is to provide an apparatus of this character, novel and improved, for maintaining the yarn in position upon-the yarn supports while imparting rotation to the yarn supports to insure subjection of all parts of the yarn skeins to the treating fluid.

These and other objects we attain by the construction shown in the accompanying drawings, wherein for the purpose of il1us-' tration, we have disclosed a preferred em-v bodiment of the invention and wherein:

Fig. 1 is a side elevation of apparatus for treating yarns, constructed in accordance with my invention, the yarn supporting unit being illustrated as partially withdrawn; 4 I

Fig. 2 is a longitudinal sectional view therethrough on line 2-2, Fig. 4;

Fig. 3 is a plan view thereof;

Fig. 4 is a section on the line 44, Fig. 2;

Fig. 5 is a section on the line 5-5, Fig. 2;

Fig. 6 is an enlarged detail sectional view through one of the spray tubes, having a yarn stick mounted thereon; and

Fig. 7 is aperspective view partially broken away of the yarn supporting unit,

. with the yarn partially applied thereto.

Referring now more particularly to the drawings, the numeral 10 generally designates a vat provided centrally with one or more inlets 11 in its bottom wall 12. Where more than one inlet is employed, as in the present instance, these'inlets will be transversely aligned and the upper ends'of the inlets will be formed as one element of a coupling as indicated at 13.

At opposite sides of the inlets the bottom wall is providedwith, depressions forming 'sumps 14 having outlets 15. At one side of the vat and preferably supported from a continuation 16 of the bottom thereof is a.

pump 17, the inlet of which is connected through a conduit 18 with outlets 15 of the sumps, and the discharge line 19 of which is connected to the inlets 11. The side Walls of the vat are provided centrally with verti'cally extending pairs of spaced ribs 20' From the top of each side wall to a point adjacent the bottom thereof, the wall is grooved as at 21, grooves 21 inclining toward one another at their lowerends.

The yarn support comprises a header 22, the lower end wall of which is provided with inlets 23, defined at their lower ends- I by downwardly tapering bosses seating upon the tapered seats 13. These bosses are guided into engagement with the seats by engagement of flanges 25 upon the edges of the header with the inner faces of the ribs 20. The width of the header is reduced at i the upper end thereof as at 26, thereby proed by a bar 32 havingvertical shafts. 33v

corresponding innumber and arrangement to the tubes 29, rotatably directed therethrough. Each shaft 33 is equipped upon its opposite ends with bevel gears 34, the lower bevel ears of the shaft operating in recesses 35 ormed in the upper wall 28 1 of the header and projecting to opposite sidev faces thereof as is clearly shown in Fig, 2. Bar 32 has on its upper surface, longitudinally spaced bearings rotatably mounting'the shaft 37 This shaft has secured thereto, pairs of oppositely directed bevel gears 38 the gears of each pair coacting with ad aoent sidesbf a pair of gears 34 upon the upper end of shafts 33.

Removabl 'mounted on opposite endsof the bevel 34upon the ldwer ends of shafts 33. Yarn sticks 39 may be bodily re moved from' the spray tubes 29 by simply sli ping them over the outer ends thereof.

- done by engaging'a hoisting mechanism with irected through and supported centrally by the bar 32 are spray tubes 44, a spray tube 44 being arranged between each pair of shafts33 and being provided with spray openings. directing the fluid downwardly against the yarn sticks of a pair of adjacent tubes 29. The center portion of each spray tube is in communicatlon with the interior of the header 22 through a port, 45 formed in the u per wall of the header and in the bar 32. pposite sides of the header have each threaded therein adjacent the bottom thereof, the inner ends of a transversely extending series of spray tubes 46, the spray tubes being longitudinally directed and as in the case of spray tubes 29 and 44 having theirouter ends closed. Spray tubes 46 correspond in number and arrangement to the spra tubes 29 and each underlie an end of a tn 9.

In 11 of an apparatus of this character, when the apparatus is to be char ed, the yarn supporting unit consisting of header 22, bar 32, and the spray pipes, is removed from the vat which may be conveniently a bail 47 connected to the bearin s 36.- The skeins S of yarn have been app ied to the several yarn sticks and are held stretched through a pipe or other tubular form 48 and each yarn stick with this form in posi tion is shdover its spray tube 46, after which the form may be removed. When all of the yarn stickshave been applied, the

'unitis partially lowered into the vat; guard sticks 49 are placed in the vat with their ends engaged in the grooves 21 and guards 50 are then placed over the upper ends of the endwalls of thevata .Each of these guards comprises a clamp section 51' to embrace the upper edge of the wall, a resilient section spaeed from the inner face of the wall and adapted, to abut the outer end face pf the tion by pump 17 section adapted to underlie the inner end of the yarn stick and to bear against the upper ortion of the outermost yarn skeins upon t e stick. The lowering of the unit is then complete, the finallowering movement placin the tapered bosses into engagev ment with t e g'uards. Attention is directed to the fact that the passage of the-yarn at I the inner ends of the stic s over the inner end hea s and engagement with the gear-' efi'ectually prevented by the fact ing will that these skeins will enga e against the side faces of the header an the heads 43 will be located over shoulders 27, Shaft 37 is then rotated and operation of pump 17 started with the result that a spray of F the treating fluid is directed against the inner faces of the skeins as they are moved through the yarn sticks by spray tubes29 and 49 and a spra is directed against the -outer faces thereo by the spray tubes 44.

Attention is also directed to the fact that because of the gearing arrangement provided, adjacent faces. of the arn skeins will be traveled in the me irection so that these yarn skeins can bebrought into much closer relation withoutdanger of tangling thereof. Treating fluid delivered to the-vat by the spray tubes 29, 44 and 46 will pass sumps 14 and be again False bottoms B disposedin the upperends of thesumps and supported from the bottom wall of the casing prevent the suction of the pump from disturbing the yarn.

It will be understood that while we have 1 5 above referred to a spray of the treating fluid, there is no actual spray, the entire casin being filled with the treatin fluid and t e spray from the tubes 44 mere y acting to provide a constant a 'tation of the no fluid which maintains a uni orm balance as regards temperature and density and, insures proper penetration of the bath through thevskein.

It will be obvious that a construction of 115 this character comprises a very compgct arrangement in which the (yarn may ve readily and ra idly place and removed. t will also be 0 vious that this construction is capable of a considerable range of chan e no and modification without in any manner eparting from the spirit of our invention, and we do not wish to be understood as limiting ourselves thereto except as, hereinafter m5 claimed.
